Could this be sabotage?
Sure. It could also be the first sign of the invasion of the Mole-Men.
That seems more than merely plausible given current tensions and the location/timing connection with NYC and UN.
I would put my money on it.
Similar events happened in Europe disguised as thieves stealing fiber optic. This does not have any sense economically, as the value in the market is zero so... either is an honest accident and is cleared in a few days, or is sabotage
trump's escalator revenge?
Yes please. Russia did it. Please move the patriotic war to the Bering Strait (Strait of America?) and leave Europe alone.
There are 400,000 to 800,000 utility strikes a year in the US. Sure you could bury (!) an instance or two of sabotage in there with an "oops".
Recently, I tried calling 811 before digging in my yard. The webpage was broken and the hotline kept me on hold forever. I gave up. Small wonder.
